Matchday six of the 2017-18 Champions League is over and we now have a completed field of 16 teams that will progress from the group stage.
Going into the final set of fixtures on Wednesday, there were still four places up for grabs, and they were taken by Liverpool, Sevilla, Shakhtar Donetsk and FC Porto.
Thirty-two teams have been whittled down to 16 for the second-round draw, which takes place shortly after the conclusion of the final group games.
With the composition of the knockout stage now decided, Goal takes a look at everything you need to know.
WHEN IS THE CHAMPIONS LEAGUE LAST-16 DRAW?
The draw for the first round of the Champions League knock-out stage will take place on Monday, December 11 at UEFA’s headquarters in Nyon, Switzerland.
It is scheduled to take place at 11:00 GMT (6:00 a.m. ET) and fans will be able to follow it via live stream on UEFA’s official website .
How does the Champions League last 16 draw work?
The draw for the last 16 of the Champions League will be a seeded draw and the winners of the eight groups will be seeded. The eight group runners-up will be unseeded.
Group winners, or seeded teams, will be away for the first-leg matches, which are scheduled for February 13/14 and 20/21, with the second-leg games due to be played on March 6/7 and 13/14.
Teams from the same group or national association cannot be drawn against one another, so, for example, Manchester United cannot be drawn against the likes of Manchester City.
However, that will change for the quarter-final draw, which will be an open draw.
WHICH TEAMS ARE IN THE CHAMPIONS LEAGUE LAST 16?
Manchester United, Paris Saint-Germain, Roma and Barcelona will be the seeded teams from Groups A-D, while Liverpool, Manchester City, Besiktas and Tottenham are the seeded teams from Groups E-H.
Real Madrid, Bayern Munich, Chelsea and Juventus make for a strong unseeded line-up, and they are joined by Basel, Sevilla, Shakhtar Donetsk and Porto.
And with Liverpool having booked their place in the knockout stage as group winners, England has become the first country to have five teams qualify for the last 16 of the Champions League.
